"Merger Agreement"), dated as of the date hereof, and


WHEREAS,
the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby are required in connection

THEREFORE, in consideration of the premises and the covenants, promises and agreements herein set forth and for other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending legally to
be bound, agree as follows:


1.                 
Liabilities of AMIB. Indemnitor represents
and warrants to Indemnitees that Schedule A hereto contains a complete and accurate listing of all Liabilities of AMIB
as of the Effective Time as defined in the Merger Agreement. Other than as set forth on Schedule A hereto, as of the Effective
Time, AMIB is not liable for any other liability, debt, obligation, deficiency, tax, penalty, fine, claim, cause of action or
other loss, cost or expense of any kind or nature whatsoever, whether asserted or unasserted, absolute or contingent, accrued
or unaccrued, liquidated or unliquidated, and whether due or to become due.


2.                 
Indemnification. In connection with the
Merger Agreement, as of the Effective Time as defined therein, Indemnitor shall assume and pay, honor and discharge when due,
and shall indemnify Indemnitors and their affiliates against, all debts, adverse claims, liabilities, judgments and obligations,
including tax obligations, of AMIB which are in excess of a total amount of $90,000.00, whether accrued, contingent or otherwise
and whether known or unknown, including those arising under any law (including common law) or any rule or regulation of any governmental
authority or imposed by any court or any arbitrator in a binding arbitration resulting from, arising out of or relating to the
assets, activities, operations, actions or omissions of AMIB, or products manufactured or sold thereby or services provided thereby,
or under contracts, agreements (whether written or oral), leases, commitments or undertakings thereof (the “Liabilities”).


3.                 
Assistance With Modification of Terms.
To the extent that any of the Liabilities of AMIB, whether set forth on Schedule A or otherwise, are, by their terms, convertible
into any capital stock of AMIB, Indemnitor shall assist with and facilitate the written modification of the terms of such Liabilities
to remove any such right to conversion. In addition to the indemnification provided under Section 2, above, Indemnitor shall defend
and indemnify the Indemnitees against any claim by any person or entity that their Liability is or was convertible to capital
stock of AMIB.
